Thanks Nodge68 some where to start
Hi. Nodge68 Thanks for your advice on the post I last put on the forum, turned out to be both a new MAF sensor and MAP Sensor straight out of the box, both knackerd. I replaced with Pierburg now pulling like a train.
no .. on it's own , without the compensating ron-box, it's too weak.
If it was remapped, then it would have made sense to map out the MAF requirements, as it's only there to mitigate black smoke production.
I will be getting my own mapped soon is this something he should just do or is it something I should ask for ?
You'll probably have to ask for it. I'm assuming the EGR functionality has remained in the MAP, as that's the only reason the MAF is there.
Isn't it there to pass MOTs - even if its not actually working.
I don’t think they care now tbh the blank on mine is shining and it’s never failed before
The EGR is there to reduce nitrogen dioxide emissions. However it's not tested as part of the MOT, as it's only active under certain running conditions.
Mine passed with a blank in place, which looks nothing like a proper EGR valve.
That's what I mean.
So they are not doing their job? Surely at some point someone will call it out and a dictate will go out to testing stations to do it properly.
Clearly not, but then cars with illegal headlamp bulbs also pass the MOT, and that's much more dangerous to other road users.
